Abstract Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

Three tricyclic [6,5,7] and six tetracyclic [6,5,5,5] novel indole alkaloids were synthesized and evaluated on triglyceride inhibitory activities for the first time. Among them, compound 4c showed the most potent activity with IC₅₀ value of 6.35 μmol·L^-1. Meanwhile, compound 4c also exhibited a good safety profile at the cellular level. Preliminary mechanism study indicated that 4c might increase intracellular lipid metabolism by activating AMPK. These results provide a novel family of lead compounds for the discovery of anti-NAFLD candidates.

Fifteen 9-substituted palmatine (1) derivatives were synthesized and evaluated for their anti-Helicobacter pylori (Hp) activities in vitro. Structure-activity relationship studies revealed that introducing appropriate substituted secondary amino group at position 9 of lead 1 might be beneficial for potency. Among them, compound 5a showed the most potential activity against metronidazole (Met) resistant Hp isolates with minimal inhibitory concentrations (MICs) of 4 μg·mL^-1, much better than that of lead 1. Compound 5a displayed satisfactory safety profile in acute toxicity assay. Molecular docking suggested that 5a might act on Hp urease. The results provided key scientific evidence for the development of 1 derivatives into a new class of anti-Hp component.

OBJECTIVE: To investigate the incidence rate of infectious diseases during hospitalization in late preterm infants in Beijing, China, as well as the risk factors for infectious diseases and the effect of breastfeeding on the development of infectious diseases. METHODS: Related data were collected from the late preterm infants who were hospitalized in the neonatal wards of 25 hospitals in Beijing, China, from October 23, 2015 to October 30, 2017. According to the feeding pattern, they were divided into a breastfeeding group and a formula feeding group. The two groups were compared in terms of general status and incidence rate of infectious diseases. A multivariate logistic regression analysis was used to investigate the risk factors for infectious diseases. RESULTS: A total of 1 576 late preterm infants were enrolled, with 153 infants in the breastfeeding group and 1 423 in the formula feeding group. Of all infants, 484 (30.71%) experienced infectious diseases. The breastfeeding group had a significantly lower incidence rate of infectious diseases than the formula feeding group (22.88% vs 31.55%, CONCLUSIONS Breastfeeding can significantly reduce the incidence of infectious diseases and is a protective factor against infectious diseases in late preterm infants. Breastfeeding should therefore be actively promoted for late preterm infants during hospitalization.

Interleukin-6 (IL-6)/signal transducers and activators of transcription (STAT) signaling pathway is closely related to the development and progression of atherosclerosis (AS). Taking Chinese natural product berberine (BBR) as the leading compound, a series of novel BBR analogues defined on different types of substituents on position 3 or/and 9 were designed, synthesized and evaluated for their inhibitory activities on phosphorylation of STAT-1 and STAT-3 induced by IL-6. The structure-activity relationship indicated that introduction of rigid fragment on position 3 or 9 was beneficial for enhancing their activities. Among them, compounds 2b and 9 exhibited the most satisfactory potency. The study revealed that the compounds 2b and 9 exhibit anti-inflammatory potencies via activating AMPK, and down-regulation of phosphorylation of STAT1 and STAT3 induced by IL-6 in HUVEC cells. These results suggest that BBR derivatives may inhibit the inflammatory response mediated by the IL-6/STAT signaling pathway through regulation of AMPK, which provides useful insight into the development of BBR derivatives for treatment of atherosclerosis.

OBJECTIVETo analyze the complications of percutaneous kyphoplasty except bone leakge for the treatment of osteoporotic thoracolumbar vertebral compression fractures.

METHODSFrom October 2008 to October 2012,178 patients with 224 osteoporotic vertebral compression fractures were treated with percutaneous kyphoplasty under local anethsia. There were 72 males and 106 females,ranging in age from 58 to 92 years old,with an average of 75.3 years,including 93 thoracic vertebrae and 131 lumbar vertebrae. The complications except bone cement leakage were analyzed during operation and after operation.

RESULTSAll operations were successful and all patients were followed up from 12 to 60 months with an average of 26.2 months. No death was found. Bone cement leakage occurred in 27 cases, about 15.1% in 178 cases; and complications except bone cement leakage occurred in 15 cases. There was 1 case with cardiac arrest,was completely recovery by cardiopulmonary resuscitation (CPR) immediately; and 1 case with temporary absence of breathing,was recovery after treatment. There were 3 cases with fall of blood pressure and slower of heart rate; 1 case with intestinal obstruction; 2 cases with local hematoma and 1 case with intercostal neuralgia. Vertebral body fractures of 2 cases were split by bone cement and the fractures of adjacent body occurred in 4 cases.

CONCLUSIONIt's uncommon complication except bone cement leakge in treatment of osteoporotic thoracolumbar vertebral compression fractures with percutaneous kyphoplasty. The complication of cardiopulmonary system is a high risk in surgery; and cytotoxicity of bone cement,nervous reflex,fat embolism and alteration of intravertebral pressure may be main reasons.

OBJECTIVE To study the effects of Qianyang Yuyin Granules(QYG)on blood pressure and renal blood flow in anesthetized normal dogs and the mechanism of hypertensive renal injury treatment.METHODS The renal blood flow,cardiac output(CO)and blood pressures were determined by PowerLab system at 15,30,60,90,120,180 min after QYG(3.08,6. 15,12.30 g/kg)administration,respectively.RESULTS Compared with the control group,QYG(12.30 g/kg)reduced sys-tolic blood pressure(SBP) significantly(P<0.05) at 120 min and 180 min,and increased the renal blood flow(P<0.05~0.01)at 90,180 min;QYG(6.15 g/kg)reduced SBP(P<0.05)at 120 min,and increased the renal blood flow(P<0.05) at 90,120 min.The effects of QYG(3.08 g/kg) were not obvious;The three QYG groups hardly affected CO (P>0.05). CONCLUSION QYG can increase the renal blood flow,improve the renal function and then reduce blood pressure.

CD146 is a newly identified endothelial biomarker that has been implicated in angiogenesis. Though in vitro angiogenic function of CD146 has been extensively reported, in vivo evidence is still lacking. To address this issue, we generated endothelial-specific CD146 knockout (CD146(EC-KO)) mice using the Tg(Tek-cre) system. Surprisingly, these mice did not exhibit any apparent morphological defects in the development of normal retinal vasculature. To evaluate the role of CD146 in pathological angiogenesis, a xenograft tumor model was used. We found that both tumor volume and vascular density were significantly lower in CD146(EC-KO) mice when compared to WT littermates. Additionally, the ability for sprouting, migration and tube formation in response to VEGF treatment was impaired in endothelial cells (ECs) of CD146(EC-KO) mice. Mechanistic studies further confirmed that VEGF-induced VEGFR-2 phosphorylation and AKT/p38 MAPKs/NF-κB activation were inhibited in these CD146-null ECs, which might present the underlying cause for the observed inhibition of tumor angiogenesis in CD146(EC-KO) mice. These results suggest that CD146 plays a redundant role in physiological angiogenic processes, but becomes essential during pathological angiogenesis as observed in tumorigenesis.
